What Is Copper Nickel Manifold Valve?

Copper nickel manifold valves are designed to control, isolate and bleed fluids in corrosive environments. These valves have excellent corrosion resistance properties against seawater, brine, and chloride solutions. Cuni Manifold valves are comes in 2 Way, 3 Way and 5 Way configuration.
